Abstract

There is provided a light source (10) for an illumination apparatus and a method of manufacturing the same. The light source (10) includes a light emitting device (100); a power unit module (200) supplying an electrical signal to the light emitting device (100); a support unit (300) having the light emitting device (100) thereon and discharging heat generated by the light emitting device (100) to the outside; and a housing unit (400) covering and protecting the light emitting device (100), the power unit module (200) and the support unit (300). The light emitting device (100) is disposed to have a height greater than that of a contact region between the power unit module (200) and the housing unit (400) with relation to a lower edge of the housing unit (400).
